Armstrong A9876 Kit Bolt Nut for 983 Inverted Bucket Steam Trap

Armstrong part A9876: kit bolt nut for the Armstrong 983 inverted bucket steam trap (980 Series).

Armstrong's 980 Series inverted bucket steam traps (models 981 and 983) are cast iron traps with a free-floating mechanism that has no fixed pivots to wear. A leverage system opens the valve against system pressure and the discharge orifice at the top of the trap stays clear of dirt.
